Keep in mind that the Sony X90L may lack the deep blacks and wide viewing angles that the LG B1 excels at. Give Feedback

The LG B1 (OLED) is very good for movies & TV, while the Sony X90L (LCD) is good.
The LG B1 OLED excels in contrast, local dimming, and black uniformity, which are essential for deep blacks and high-quality picture during movie scenes, especially in dark environments. However, the Sony X90L LCD, while also providing good performance for movies with decent contrast and local dimming, may not match the LG B1 in these aspects but offers wider viewing angles and better color accuracy right out of the box, making it a versatile choice for mixed usage.

Although they have very similar scores, PerfectRec considers Sony X90L (LCD) to be excellent for news, talk, & other TV, while the LG B1 (OLED) is very good.
The LG B1 OLED excels in upscaling lower resolution content and delivers pure blacks due to its OLED technology, which is significant while watching news and talk shows, but it's not as bright as some LCD TVs which can affect viewing in well-lit rooms. The Sony X90L LCD, on the other hand, offers excellent SDR brightness making it more suitable for bright rooms and provides very good upscaling, but it lacks the perfect blacks achievable by OLEDs which may affect contrast during such programs.
